Possible Thyroidal Involvement in a Case of Fabry Disease

Abstract

Endocrinological evaluations of a 48-year-old man with Fabry disease revealed low levels of serum thyroid hormones and high levels of serum thyrotropin (TSH), indicating that the patient had primary hypothyroidism. Also, an exaggerated growth hormone (GH) response to hypoglycemic stimuli was observed. Thin layer chromatography of the lipid extract of the thyroid gland obtained by biopsy demonstrated marked accumulation of ceramide trihexoside (CTH) and ceramide dihexoside (CDH). These findings strongly suggest that thyroid hypofunction and hypothalamic dysfunction could be involved in Fabry disease. © 1994, The Japanese Society of Internal Medicine. All rights reserved.
